During IODP Leg 317 off the east coast of New Zealand, three continental shelf sites (U1351, U1353 and U1354) and one continental slope site were cored. Sedimentary sequences representing shallow water depositional cycles were recovered and ranged from Upper Miocene to recent in age. One of the most widely used tools in the academic and scientific realm by onboard paleontologists to quickly determine such ages, along with foraminifera, are calcareous nannofossils. Adequate ages are highly dependent on the amount of time the shipboard paleontologist has to scan samples for biozone markers, and in some instances, zonal markers are unable to be found. Therefore, it is sometimes necessary for a secondary, post-cruise analysis of sediments to confirm the biostratigraphy developed during the cruise. Secondary objectives for this project include development of calcareous nannofossil abundance counts to analyze population dynamics, richness, evenness, and diversity as well as examination of ages and abundances of reworked and transported nannofossil assemblages in order to better understand transport mechanisms and sediment sourcing of the area. This additional onshore post-cruise analysis will allow for a more detailed study of the biozonation of the region as well as general assemblages. It is also believed that nannofossil abundances/assemblages undergo a profound change across sequence stratigraphic boundaries. This work aims to analyze these changes and determine the feasibility of using nannofossils to study these depositional cycles. Simple smear-slides have been prepared from ~100 samples and are currently undergoing semi-quantitative analysis using an Axioscope II light microscope. Shipboard biostratigraphic analysis of calcareous nannoplankton is crucial for accurate determination of stratigraphic ages due to their diversity, rapid evolution/mutation, and abundance in marine sediments. Establishing good age control allows for correlation with other proxies to develop precise chronology of cored sediments.
